Login page error for AD user

Hello,

I am trying to sync users from windows server 2012 LDS with Drupal 8 site.

I have followed the following steps to setup the LDAP module in Drupal8.
https://www.drupal.org/node/1023900
https://www.drupal.org/node/1302032
https://www.drupal.org/node/1053748

I have also added the following changes:
Added function getUserDataFromServerByAccounterDataFromServerByAccount($drupal_user, $sid = NULL, $ldap_context = NULL) {}
in ldap_servers/ldap_servers.module b/ldap_servers/ldap_servers.module

public function getUserDataFromServerByAccount($account, $id, $ldap_context = NULL) {
- $identifier = LdapUserConf::getUserIdentifierFromMap($account->id());
+ $identifier = LdapUserConf::getUserIdentifierFromMap($id);
in ldap_servers/src/ServerFactory.php b/ldap_servers/src/ServerFactory.php

In ldap_authetication.module on line no : 695
I have done the following changes
From --> $drupal_account = $auth_conf->ldapUser->provisionDrupalAccount(NULL, $user_values, NULL, TRUE);
To --> $drupal_account = $auth_conf->ldapUser->provisionDrupalAccount(NULL, $user_edit, $ldap_user, TRUE);

After all the configuration changes,
I am trying to login with a user in the LDS account but I am getting the following error.

The website encountered an unexpected error. Please try again later.

Please let me know if anybody have faced the same issue.

Same kind of issue happened in D7 and they have a solution in this link https://www.drupal.org/node/1910354 but this solution did not help me.
